Less invasive techniques, including laparoscopic and robotic surgeries, have transformed colon and rectal surgeries. Small incisions mean less blood loss, less discomfort, a shorter hospital stay and a faster recovery. There is also a lower chance of infection and a less noticeable scar.

At the Weill Cornell Medicine Colon and Rectal Surgery Division, our surgeons specialize in many minimally invasive surgical techniques, producing the best surgical experiences and outcomes for our patients. In fact, our surgeons continue to revolutionize the way minimally invasive surgery is performed, providing more efficient, effective treatment options for patients.

Conditions We Treat with Minimally Invasive Colon and Rectal Surgery

Our surgeons use minimally invasive surgical techniques to treat:

● Colon cancer

● Rectal cancer

● Rectal prolapse, which occurs when part of the large intestine (the rectum) stretches and protrudes from the anus. Surgery puts the rectum back in place.

● Pelvic floor disorders, such as vaginal prolapse

● Inflammatory bowel disease, including Crohn’s disease, diverticulitis and ulcerative colitis

Minimally Invasive Colon and Rectal Surgery Options

At Weill Cornell Medicine, our team offers the most advanced and comprehensive minimally invasive colon and rectal surgery options available.

Laparoscopic colon surgery or colectomy: Laparoscopic surgery is a minimally invasive technique in which small tubes with a light and camera attached are inserted into small incisions (cut) in the abdomen. The camera projects a high-definition image of the body onto a screen in the operating room. This image guides the surgeon to perform the specific surgery needed, without the need for a large incision.

Laparoscopic rectal prolapse repair: This procedure uses several small incisions in the abdomen. The surgeon inserts special surgical tools and a tiny camera through the abdominal incisions to repair the rectal prolapse.

Transanal endoscopic microsurgery (TEM) and transanal minimally invasive surgery (TAMIS): Both TEM and TAMIS are techniques that allow surgeons to remove polyps and early-stage cancerous tumors in the rectum using a port and microscopic lens placed in the rectum. This technology preserves a patient’s anal sphincter muscle control.

Robotic-assisted surgery: Robotic surgery, or robot-assisted surgery, involves the use of surgeon-guided, robotic arms that allow the surgeon to perform complex procedures with more precision and control than is possible with conventional techniques. With its enhanced visualization, it is most commonly used for tumors located in the sigmoid (the lower portion of the large bowel) and rectum.
